Monitor problem

I would disagree here. For display photographic images, almost no work is
being done by the graphics card. Any basic card running as a frame buffer
(with say 8MB) wouldn't perform much different from the 512MB card that
seems to be standard. It is really only in 3D games or 3D display managers
like Compiz where they will have appreciable benefit. With the right program
your card could easily display 25 photos per second with no flicker - this
is what any movie player needs to do!

Both Picasa and F-spot while feature rich, are probably rely too much on the
CPU to do their work. Picasa is basically a Windows program running in
emulation (using WINE), and F-spot is written using mono, which is a clone
of the .Net framework. Probably the slickest way to view photos (and do
basic manipulation) is gthumb. It used to be the default photo program until
Hardy (you may need to install it from synaptic if you did a fresh install
of Hardy).

I just did a 3-way test of the above 3 programs doing full-screen "paging"
through some photos and gthumb is far quicker (at least 3-4 times) than the
other two for this function. (I am viewing 2592x1944 images on a 1400x1050
so it has to do non-integer scaling/dithering to display these - which is
where I think your problem was occuring.)
